[check_postgres] hot_standby_delay time metric?

[John Robison]

When I run check_postgres with the hot_standby_delay action, it will output
something like this:

POSTGRES_HOT_STANDBY_DELAY OK: DB "mydb" (host:myserver) 0 | time=0.09s
replay_delay=0;1024;2048  receive-delay=0;1024;2048

What is the time that is being referenced there (time=0.09s)? Is that the
lag between the two servers, measured in seconds? Or is that the amount of
time that it took to run this query?


Thanks,

John.
